Patented Sept. 15, 1931 SATES GLEN OBRIEN, OF TROY, KANSAS WATER COOLINGSYSTEM Application led August .30, 1930. Serial No. 478,924.

My invention relates to a system of cooling water drawn from the citymains or other source of supply and an important feature of theinvention resides in means whereby the water may be reduced to atemperature which will render it agreeable for drinking purposes withoutcost other than that of installing the system, as the use of ice orother refrigerants which must be renewed from time to time is notnecessary.

rThe present system may also be used to advantage for supplying coolwater to the cooling apparatus disclosed by my copending applicationfiled July 16, 1930, Serial Number 468,222.

In order that the invention may be fully understood, reference will nowbe had to the accompanying drawings, in which:

Fig. 1 is a sectional View showing the system installed and ready foruse.

Fig. 2 is a detail of a coiled pipe and fins forming important featuresof the invention.

Fig. 3 is a detail perspective view of one of the fins.

Fig. 4 is a. side elevation of a three-way valve employed in carryingout the invention.

Referring in detail to the dierent parts, 2 designates the city mainfrom which the service pipe 4 leads to a building A, the iiow of waterthrough the service pipe 4 being initially controlled by a curb cock 6of any well known construction.

8 designates a three-way valve of any suitable construction which isconnected to the service pipe 4, preferably at a point within theproperty line of the building A.

10 designates a coiled pipe of suitable size coupled at its inlet andoutlet ends to pipes 12 and 14, respectively. The pipe 12 is connectedat its upper end to the valve 8, while the pipe 14 is connected at itsupper end to the service pipe 4 at a point in the rear of the valve 8.

The coil 10 is equipped at intervals with fins 16 and the variousconvolutions of the coil are supported in spaced relation to each otherby means of suitable racks 18.

When installing the system a hole B of sufficient diameter to admit thecoil 10 and ad;50 jacent parts is sunk twenty or thirty feet in theground where the temperature usually ranges from fifty to sixty-threedegrees F. Should water be found at the above depths the pipe 10 and thefins 16 are submerged in 15.55 the water to obtain the cooling ei'ectsthereof, but if no water appears in the hole B the latter is filled withsand or soil which is caused to pack snugly around the convolutions ofthe coil 10 and around the lins 16, sogg that the low temperature of thesoil will be imparted to the aforementioned parts and cool the water inthe coil.

After the hole B has thus been filled with sand or soil the valve 8 isadjusted to cause 65 the water in the service pipe to flow from thelatter through the pipes 12, 10 and 14 and thence into the service pipefor use in the building A. Should it be desirable at any time to havethe water ilow through the service pipe 4 without traversing the bypassformed by the pipes 12, 10 and 14, the threeway valve 8 is adjustedaccordingly.

By making the coil 10 and its associated parts of copper or otherrust-resistant material said coil and associated parts will last for aconsiderable period of time, and since the natural temperature of theearth or water surrounding the coil 10 and the fins `16Vis utilized forcooling the water flowing through I said coil, an abundance of cooledwater is obtained without cost other than that of installing the system.

From the foregoing descriptionit is apparent that I have provided asystem whereby water may be economically cooled, and while I have shownone form of the invention it is to be understood that I reserve allrights to such other forms and modifications as propl0 erly fall Withinthe spirit and scope of the invention as claimed.

Having thus described my invention, what I claim and desire to secure byLetters Patent,

In a system of the character described, the combination With a Watermain and a service pipe leading therefrom, 2t three-Way valve connectedto said service pipe, a by-pass con nected at one end to the servicepipe and at Y its opposite end of said valve and including a coiledpipe, and means for holding the convolutions of said coiled pipe inspaced relation to each other.

In testimony whereof I aliX my signature.

GLEN OBRIEN.
